CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N o. 690,297, dated December 31, 1 901.

I Application filed July 8,1901. Serial No. 67,472. (No model.)

-pending application, Serial No. 60,761, filed May 17, 1901; and one of the objects of the invention is to provide a simple device of this character wherein friction is greatly reduced and which is automatic in action and especially intended for application to passenger-cars.

The improved knuckle hereinafter described is applicable, of course, to draw-heads of the kind disclosed in said application and,

like such prior knuckle, it is of the duplex` type, it having complemental jaws at its opposite ends, so that if the knuckle be broken or in any wise injured it can be reversed and rendered just as useful as a new one. The

Vdraw-head in the present case has three sets lof vertically-alined or registering holes to re- .'ceive one or two locking-pins, so that when necessary the knuckle can be dead-locked. The draw-head incloses the lock for the knuckle, and in this application this lock is lifted to release the jaw by means situated below the latter.

Thev invention is clearly shown in the accompanying drawings, forming a part of this specification, in which- Figure 1 is a plan view of a car-coupling involving my present improvements and showing the equalizer. Fig. 2 is a face view of the samerwith the duplex coupling-jaw removed from the draw-head. Fig. 3 is a transverse section taken in the line 3 3, Fig. 2. Figs. 4

and 5 are perspective views of the duplex jaw and locking member therefor detached. Fig. l

stem, as 13.

The coupling member, which is made of draw-head has projecting walls GO, horizon- 65 tally located one above the other and which house the projecting parts of the duplex jaw, thereby avoiding any friction, and what are shown as the right ends of these projecting walls have sloping or slanting guide-surfaces, 7o as 61, the upper one being inclined upward and the lower downward. These sloping snrfaces better enable the coupling of cars when the draft-lines thereof are not equal.

The duplex jaw or coupling member 14 has 75 centrally thereof the vertical lip or extension 62, the function of which is to make the said jaw operate more easily and accurately, it being seen that said lip or extension is of the same height as the jaw.

The draw-head has two pin-holes, as 2O and 21, the first-mentioned one being adapted to register with what is the rearmost hole of the duplex jaw when the same is closed. Should the forward or pivot hole break out, all that 8 5 is necessary to safely transport the car to the end of the journey is to place a pin through the rear registering holes, so as to dead-lock the jaw. The duplexl coupling-jaw swings upon the 9o central pivot-pin 14', and should one ofits jaws become worn or broken from any cause this pivot-pin can be removed and the -jaw reversed, whereby, in eect, a new part is se-rg., cured.

The draw-head and coupling-jaw with respect to the holes just set forth are similar to those set forth in my said prior application; but in the present case I form in the drawhead a third hole, as 63, and it will be seen roo that these holes are triangularly arranged. This hole 63 is adapted to receive a pin, (not shown,) which is passed through the working end or jaw of the duplex coupling-jaw inter locked with the one illustrated, and 'the insertion of this pin securesadead-lock without any delayin case the knuckle or jaws in either draw-head become totally disabled.

The locking member for the jaw is denoted by 22, and it comprises a back piece, as 23, which may be ot' rectangular plate form, which is vertically slidable in a substantially similar shaped vdepression or hollow in the rear Wall of the chamber of the draw-head, and the opposite side walls of the depression guide said back piece. One of the wall-s of this depression is shown as beveled and as fitting over the correspondingly-shaped edge of the back piece, so as to limit the oscillation of the latter. The back piece 23 has on its forward face the flanges 24, approximately triangular in shape, and one edgefof each iange is rounded, as at 24', to engage against the correspondinglya'ounded surface of the inner jaw of the duplex coupling member 14, so as to lock' and firmly hold the same. The top wall' of the chamber of the draw-head has 'a pocket, as 25, shaped to agree in outline with the superposed flanges 24, and the lower flange is adapted to receive theupper threaded vend ot' a pin, as 26, depending from thelocking member and extending through a suitably-placed perforation in the under side of the draw-head.

To release the duplex coupling-jaw 14, the

vlocking member 22 will be lifted by an upward thrust on the pin 26, as hereinafter described, until the upper tiange 24 is carried into the pocket 25. This will bring the lower 'iiange into horizontal line with the transverse opening or aperture 27 of the inner jaw, so

' that the coupling member will be released and depending from the under side of the draw-- head. y This lever is supported by a cotterkey bolt, as 67, and may be operated by a rod (not shown) mounted upon the car in some suitable place and manner. When the long arm of said lever is swung outward, the pin 26 is raised, so as to lift the locking member- 22, and thereby release the compound jaw 14.

The stem or bar 13 is hollow, and at the inner and reduced end of the same are two seats, as 68, each having two l1oles,as 69, therein,this construction being for the purposes of attaching wrought-iron or steel bars for extending the stem to any length desired.

In Fig. l I have shown au equalizer; but as the same forms no part of the invention forming the basis of the appended claims it is not illustrated in detail.

By the use of my improved coupler in case of derailment the train would continue coupled after derailment and prevent the cars appended claims may be made.
